ATTORNEYS TAPE RECORDER WITH AUTOMATIC RELEASE FROM FAST SPEED BYSENSING PAUSES BETWEEN RECORDED MATERIAL This invention relates to atape recorder, and more particularly to a tape recorder capable ofdetecting a pause portion between signal bands on the tape automaticallyso that a signal band, such as a tune of music, is reproduced from itsbeginning.

Music tape usually has a plurality of tunes prerecorded thereon. If onewants to hear the second tune or the third tune on the tape from itsbeginning, he has to operate a control knob or operating keys many timesbefore he finds out the beginning of the desired tune in a conventionaltape recorder. Such trouble will also occur when he wants to hear thesame tune repeatedly from its beginning.

The pause portion can not be detected exactly even with the taperecorder having a tape counter, since an indicated number of the tapecounter does not always exactly correspond with the length that a tapehas been moved. Moreover, it is necessary for him to memorize the numberindicated by the tape counter in advance.

It is, therefore, a general object of the present invention to provide anovel tape recorder. wherein a pause portion between signal bands isautomatically detected while the tape is moving at a higher speed than atape-playing speed.

It is another object of the present invention to provide an improvedtape recorder wherein winding means for moving a tape at a higher speedthan a tape-playing speed is brought into its inoperative state by arotational force of a motor upon detection of a pause position on thetape.

It is still another object of the present invention to provide a taperecorder as defined in the preceding paragraph with novel means reliablein operation for detecting the pause portion accurately.

It is still another object of the present invention to provide animproved tape recorder wherein a signal band is automatically reproducedfrom its beginning after a tape is moved at a higher speed than atape-playing speed by using novel holding means for holding both thetape moving means and the winding means in their operative states.

These objects of the present invention are achieved by a tape recorderwhich comprises a tape moving means for moving a tape at a tape-playingspeed, winding means for moving said tape at a higher speed than saidtape-playing speed, operating means for bringing said winding means intoits operative state, holding means for holding said operating means atan operative position, a transducing head for reproducing signalsrecorded on said tape according to move ment of the tape, an electricamplifier connected to said head, a detecting circuit coupled to saidamplifier to detect a pause portion between signal bands on said tape,an electromagnet responsive to said pause portion detected by saiddetecting circuit while said tape is being moved by said winding means,driving means driven by a motor, and releasing means for releasing saidoperating means from said holding means upon engagement of said drivingmeans with said releasing means so that said winding means is broughtinto its inoperative state when said releasing means is actuated by saidelectromagnet upon detection of said pause portion on said tape.

The invention will become fully apparent from the following detaileddescription of one embodiment of the invention taken in conjunction withthe accompanying drawings, in which:

FIG. 1 is a schematic plan view of the tape recorder according to thepresent invention;

FIG. 2 is a schematic plan view to FIG. I, but in its playing state;

FIG. 3 is a schematic plan view of the tape recorder similar to FIG. I,but in its tape-winding state where the tape moves in a first directionat a higher speed than a tape-playing speed;

FIG. 4 is a schematic plan view of the tape recorder similar to FIG. 1,but in its tape-winding state where the tape moves in a second directionat a higher speed than a tape-playing speed;

FIG. 5 is a diagrammatic illustration of electric circuits used in thetape recorder of the present invention; and

of the tape recorder similar takeup reel 42.

FIG. 6 is a fragmentary view of a recorder of the present invention.

Referring to FIG. I, a motor 10 is attached on a chassis 12. A rotatingbody 14 which consists of a capstan l6 and a flywheel 18 is rotatablymounted on said chassis 12 by a suitable bearing (not shown). An endlessbelt 20 is disposed between said motor 10 and flywheel 18 so that saidrotating body 14 is rotated in a direction of an arrow 22 by the motor10. Y Y

A pressure roller 24 is rotatably mounted on an end of an arm 26 whichis pivotally mounted on a shaft 28 secured to the chassis 12. Thepressure roller 24 is biased toward said capstan 16 by a spring 30connected to said arm 26.

A transducing head 32 is mounted on said arm 26. At a position faced tosaid head 32, the chassis 12 is provided with a pad 34 adhered to a leafspring 36. A magnetic tape 38 wound on a supply reel 40 is forwardedfrom said supply reel 40, through a tape-moving path between said pad 34and the head 32 and between the capstan l6 and the pressure roller 24,to a takeup reel 42 so as to be wound thereon.

When the tape 38 moves in the direction of an arrow 44 at a tape-playingspeed upon engagement of the pressure roller 24 with the capstan 16 in aplaying state of the tape recorder in this embodiment, the tape 38 iswound on the takeup reel 42 through a frictional slipping mechanism.Since the details of such slipping mechanisms are well known in the art,it will be unnecessary to describe them herein. There is no need to havesuch slipping mechanism in case of "a continuous loop-type taperecorder, a so called tape recorder for use with an endless tapecartridge.

The tape 38 is moved at a higher speed than the tape-playing speed bywinding means which will be explained in detail hereinafter.

In this embodiment of the present invention, such winding meanscomprises a first winding means for moving the tape in a first directionindicated by the arrow 44 and a second winding means for moving the tapein a second direction reverse to the arrow 44. The takeup reel 42 isplaced on a reel roller 46 which is rotatably mounted on a shaft 48secured to the chassis 12. The supply reel 40 is placed on a reel roller50 which is rotatably mounted on a shaft 52 secured to the chassis 12.An idler wheel 54 is rotatably mounted on a shaft 56 secured to an endof an arm 58 which is rotatably and slidably mounted on a shaft 60secured on the chassis 12. A spring 62 is connected to arm 58 to biasthe idler wheel 54 toward a position between the flywheel 18 and thereel roller 46.

When the idler wheel 54 is brought into driving engagement with theflywheel l8 and with reel roller 46, the reel roller 46 rotatescounterclockwise so as to wind the tape 38 on the In this case, the tape38 moves in the direction of the arrow 44 at ahigher speed than atape-playing speed.

Construction of second winding means is as follows. A lever 64 ispivotally mounted on a shaft 66 secured on the chassis l2, and has apulley 68 mounted rotatably at one end thereof. A belt 70 is disposedbetween pulley 68 and the reel roller 50.

Lever 64 is biased counterclockwise by a spring 72 attached to a secondend 74 of the lever 64 so as to engage belt 70 wound on the pulley 68with the peripheral surface of the flywheel 18. When belt 70 is engagedwith the flywheel 18, the reel roller 50 rotates clockwise so as to windthe tape 38 on the supply reel 40. In this case, the tape 38 moves in adirection opposite to the arrow 44 at a higher speed than thetape-playin g speed.

When the tape recorder, is stopped, the winding means is maintained inits inoperative state by operating means which will be described indetail hereinafter.

The operating means includes a play key 76, a first winding key 78, asecond winding key and a stop key 82. The play key 76 is coupled to thetape-driving means in a manner that will be explained herein. Play key76 is secured to a front end of a plate 84 which is slidably mounted onthe chassis 12 by guide pins 86 and 88. Plate 84 has a pin 90 secured toan end portion thereof. A spring 92 attached to plate 84 urges the playkey Y76 and the plate 84 in a direction indicated by an tape used in thetape arrow 94 so as to keep them at the inoperative position as shown inFIG. 1.

When the play key 76 is positioned at its inoperative position, the pin90 on the plate 84 drives the arm 26 clockwise so that the head 32 iskept apart from the tape 38 and the pad 34, and the pressure roller 24is kept apart from the tape 38 and the capstan 16 as shown in FIG. I.

The first winding key 78 is coupled to the first winding means in amanner that will be explained herein. First winding key 78 is secured toa front end of a plate 96 which is slidably mounted on the chassis 12 byguide pins 98 and 100. The other end of plate 96 forms a hook portion102 which engages with a pin 104 secured to an end of the arm 58. Aspring 106 attached to plate 96 urges the first winding key 78 and theplate 96 in the direction indicated by the arrow 94 so as to keep themat the inoperative position as shown in FIG. 1.

When the first winding key 78 is at this inoperative position, the hookportion 102 of the plate 96 pulls the pin 104 on the arm 58 so that theidler wheel 54 is kept apart from the reel roller 46 as shown in FIG. I.

The second winding key 80 is coupled to the second winding means ina'manner that willbe explained herein. Second winding key 80 is securedto a front end of a plate 108 which is slidably mounted on the chassis12 by a guide pin I and a pin 112 secured to the end 74 of the lever 64.A spring 114 attached to plate 108 urges the second winding key 80 andthe plate 108 in the direction indicated by the arrow 94 so as to keepthem at the inoperative position as shown in FIG. 1. When the secondwinding key 80 is in this inoperative position, the plate 108 drives thepin 112 and swings the lever 64 clockwise so that the belt 70 around thepulley 68 is kept apart from the flywheel 18 as seen in FIG. I.

A stop key 82 is secured to a front end of the plate 1 16 which isslidably mounted on the chassis 12 by guide pins 118 and 120. A spring122 attached to plate I 16 urges the stop key 82 and the plate 116 inthe direction indicated by the arrow 94 so as to keep them at theinoperative position as shown in FIG. I.

These keys of the operating means are locked at their operative positionby holding means which will be explained in detail hereinafter. Theholding means includes a first holding device I24 for holding the playkey 76, and a second holding device I26 for holding the first and secondwinding keys.

First holding device 124 is slidably mounted on the chassis 12 by guidepins 128 and 130, and is biased by a spring 132 in the direction of anarrow 134. First holding device 124 has a pin 136 secured thereto, whichis capable of engaging with a projection 138 formed on the plate 84.Device 124 also has a pin 140 secured thereto, which is capable ofengaging with a sloped sidewall 142 of the plate 116. Second holdingdevice I26 is slidably mounted on the chassis 12 by guide pins 130 and144 and is biased by a spring 146 in the direction of the arrow I34.Holding device 126 has a pin 148 secured thereto, which is capable ofengaging with a projection 150 formed on the plate 90. Device 126 alsohas a pin 152 secured thereto, which is capable of engaging with aprojection 154 formed on the plate 108.

When an operator pushes the play key 76 in the opposite direction of thearrow 94, the play key 76 is locked at its operative position by thefirst holding device 124 in such a way that a stepped portion of theprojection 138 of the plate 84 is locked by the pin 136 on the firstholding device 124 as shown in FIG. 2. This allows the arm 26 to swingcounterclockwise under the biasing force of spring 30 so that thepressure roller 24 is pressed against the capstan I6. The capstan 16moves the tape.38 in the direction of the arrow 44 at the tape playingspeed in cooperation with the pressure roller 24.

The first winding key 78 is locked at its operative position by thesecond holding device 126 in such a way that a stepped portion of theprojection 150 of the plate 96 is locked by the pin 48 on the secondholding device 126 as shown in FIG. 3.

Since the hook portion I02-of the plate 96 moves away from the pin 104on the arm 58, the idler wheel 54 is pressed against 4 both the flywheell8 and the reel roller 46 by the spring 62. At the same time, a pin 156secured to the plate 96drives counterclockwise a lever 158 which ispivotally mounted on a shaft 160 secured to the chassis 12.Consequently, a pin I62 atfixed to an end of the lever I58 swings thearm 26 clockwise slightly so that the pressure roller 24 is separated bya short distance from the capstan 16.

The transducing head 32 shifts slightly from the pad 34 and occupies asecond position as shown in FIG. 3, while still maintaining pressingengagement with the tape 38. This shift of the head 32 reduces thepressure between the head 32 and the pad 34.

This decreases the necessary torque for rotation of the reel roller 46which is driving the tape 38 to wind'the tape on the takeup reel 42.Thus, the tape 38 moves in the direction of the arrow 44 at a higherspeed than the tape playing speed.

When the operator pushes the second winding key in the oppositedirection of the arrow 94 from the playing state of the tape recorder inFIG. 2, the second winding key 80 is locked at its operative position bythe second holding device 126 in such a way that a stepped position ofthe projection 154 of the plate 108 is locked by the pin 152 on thesecond holding device 126 as shown in FIG. 4. The lever 64 swingscounterclockwise under the biasing force of the spring 72 upon mc'iv'evment of the plate 108 in the opposite direction of the arrow 94 so thatthe belt 70 around the pulley 68 is brought into engagement with theflywheel 18. At the same time, a pin I64 I secured to the plate 108drives the lever I58 counterclockwise so that the pin 162 swings the arm26 clockwise slightly. Accordingly, the pressure roller 24 .is separatedat a short distance from the capstan 16. The head 32 is also displacedslightly from the pad 34 and occupies the second position as shown inFIG. 4. Thus, the tape 38 moves in the opposite direction of the arrow44 at a higher speed than the tape playing speed.

The keys will be restored to their inoperative position when theoperator pushes the stop key' 82 in the opposite direction of the arrow94. The sloped portion 142 of the plate I16 drives the pin to move thefirst holding device 124 in the opposite direction of the arrow 134 inFIG. 3. The plate 84 is released from locking engagement with the pin136 so that the play key 76 is moved in the direction of the arrow 94 bythe spring 92 to return to its inoperative position. Upon above movementof the first holding device 124, a pin 168 on the device 124 drives thesecond holding device 126 in the same direction. The plate 96 isreleased from locking engagement with the pin 148 so that the firstwinding key 78 is moved in the direction of the arrow 94 by the spring106 to return to its inoperative position. The second winding key 80 isalso restored to its inoperative position in the same manner describedabove, under the biasing force of spring 114.

The first winding key 78 and the second winding key 80 can also bepushed even when the tape recorder is in the inoperative position shownin FIG. 1. In this case, the transducing head 32 does not engage withthe tape 38, since the play key 76 has not been pushed. On the otherhand, the tape 38 is wound on the takeup reel 46 or the supply reel 50by the winding means in the same manner as described above.

First winding key 78 and second winding key 80 are also restored totheir inoperative position automatically by releasing means incooperation with driving means which will be explained in detailhereinafter. Driving means in this embodiment is an actuating devicewhich consists of a plurality of actuating elements 170 secured to theflywheel 18.

Construction of releasing means in this embodiment is as follows. Areleasing device I72 is pivotally mounted on the shaft 28 and has an endportion 174 thereof capable of actuating a bent portion 176 of thesecond holding device 126. A

lever [78 is pivotally mounted on a shaft I80 secured to the other endof releasing device 172 and has a stepped portion 182 formed at one endthereof.

Lever 178 is biased counterclockwise by a spring 184 to shift thestepped portion 182 out of the rotation locus of the actuating elements170 so that the stepped portion 182 is not contacted by one of theactuating elements 170. An electromagnet 186 is positioned in thevicinity of the other end 186 of the lever 178. Since lever 178 is madeof magnetic material, such as steel, in this embodiment, the lever 178is caused to swing clockwise upon energization of the electromagnet 186.

With reference to FIG. 5, electric circuits used in this tape recorderwill be explained.

An electric amplifier 190 is connected to the transducing head 32 toamplify signals which are reproduced from the tape 38 by head 32. Thetape 38 has a plurality of signal bands 192 prerecorded thereon as shownin FIG. 6. Each signal band 192 can be for instance, one tune of music.A pause portion 194 in an appropriate length exists between adjacentsignal bands 192.

A detecting circuit 196 is connected to amplifier 190 through a switch198 remove the signals from the amplifier 190 as shown in FIG. 5. Switch198 on the chassis 12 (in FIG. 1), is brought into a closed state uponcounterclockwise motion of the lever 158. Therefore, the detectingcircuit will not be brought into its operative state unless the firstwinding key 78 or the second winding key 80 is pushed. An out put signalof the detecting circuit 196 is supplied to the electromagnet 186. Whenone of said pause portions 194 on the tape 38 comes to a positioncorresponding to the head 32, the detecting circuit 196 detects thischange of signal level so as to energize the electromagnet 186.

It is possible to use a tape on which a special control signal, such as60 Hz sine wave, is recorded at the pause position. However, in thiscase, the detecting circuit should be replaced by a detecting circuitwhich can detect said control signal through a filter circuit.

The operator can hear the signal, such as music, on the tape, when hepushes the play key 76 as shown in FIG. 2. If the operator wants to skipa signal of a certain signal band, he can hear the next signal band fromits beginning by only one operation of the first winding key 78.

When one pushes the first winding key 78 at the playing state of thetape recorder as shown in FIG. 3, the first winding means is brought toits operative state as described above. Then, the tape 38 moves in thedirection of the arrow 38 at a higher speed than the tape-playing speed.The head 32 picks up the signal on the tape according to the movement ofthe tape, since the head 32 engages with the tape 38 at its secondposition. When the pause portion between the signal band which has beenreproduced and the following signal band comes to the positioncorresponding to the head 32, the detecting circuit 196 detects suchpause portion and energizes the electromagnet 186. Upon thisenergization, the electromagnet 186 pulls the end 188 of the lever 178so as to swing lever 178 clockwise as shown by the dot-dash lines inFIG. 3. The stepped portion 182 of the lever 178 is contacted by one ofthe actuating elements 170 upon rotation of the flywheel 18.Consequently, the releasing'device 172 swings counterclockwise so thatthe end portion 174 of device 172 drives the bent portion 178 of thesecond holding device 126 in the opposite direction of the arrow 134.The first winding key 78 returns to its inoperative position when theprojection 150 of the plate 96 is released from the pin 148.Accordingly, the first winding means is brought into its inoperativestate. At the same time, the arm 26 swings counterclockwise by thespring 30 to press the pressure roller 24 against the capstan 16, sincethe play key 76 has remained in its operative position. Then, the tape38 moves at the tape-playing speed, and the following signal band isreproduced by the head 32 from its beginning.

If the operator wants to hear a certain signal band repeatedly, he canhear such signal band from its beginning by only one operation of thesecond winding key 80.

When one pushes the second winding key 80 while the tape recorder isplaying as shown in FIG. 4, the second winding means is brought to itsoperative state as described above.

Then, the tape 38 moves in the opposite direction of the arrow 44 at ahigher speed than the tape-playing speed. When the pause portion infront of the beginning of the signal band which has been reproducedcomes to the position corresponding to the head 32, the detectingcircuit 196 detects such pause portion and energizes the electromagnet186. Upon this energization, the electromagnet 186 pulls the end 188 ofthe lever 178 so as to swing lever 178 clockwise as shown by thedot-dash lines in FIG. 4. The stepped portion 182 of the lever 178 iscontacted by one of the actuating elements 170. This causes thereleasing device 172 to drive the second holding device 126 in theopposite direction of the arrow 134. The second winding key returns toits inoperative position, and the second winding means is brought intoits inoperative state. At the same time, the arm 26 swingscounterclockwise by the force of spring 30 to press the pressure roller24 against the capstan 16, since the play key 76 has remained in itsoperative position. Then the tape 38 moves at the tape playing speed inthe direction of the arrow 44, and the same signal band is re peatedlyreproduced by the head 32 from its beginning.

In the above embodiment, the play key 76 is used in order to bring thetape recorder into its playing state. However, it is not alwaysnecessary to provide such play key, especially in a tape recorder forautomobile use, which is recently available in the market. Such a taperecorder uses a tape cartridge so that the tape recorder is brought intoits playing state automatically when the tape cartridge is inserted intoa slot of the tape recorder.

Further, a single transducing head in the above embodiment is used notonly for reproduction of signal bands but for detection of a pauseportion on the tape. However, it will be readily possible to use twoheads, one for reproduction of signal bands and the other for detectionof pause portions.

It will be apparent to those skilled in the art that variousmodifications may be made without departing from the spirit of theinvention. The above described specific examples are intended merely toillustrate various facets in certain selective embodiments of theinvention;
